“…Therefore, the indirect solar dryer, with a solarthermal converter, cylindrical-parabolic as an air insolator, seems to be a viable technical-economic compromise, avoiding the cost of improving the thermal performance of a flat plate collector, an alternative to the low energy density of the incident solar radiation [5] and finally, a good response to the problem previously mentioned [4]. To confirm this conclusion, tests related to the drying of okra were conducted.…”

According to Arthur S. EDDINGTON (1921): "I can prove nothing to you whether you do not let me make any measurements. Measurement is for me the only way to find the laws of nature. I am not a metaphysician". In order to confirm the performances of the indirect solar dryer, with cylindricalparabolic collector, the performances noted by the numerical results and validated by the value of the Square Root of the Mean Systematic Error, RMSE, equal to 4.5°C, between the numerical and experimental temperatures of the heat transfer fluid, at the entrance of the drying cage, experimental tests of the said dryer were carried out, via the drying of the variety, Clemson spineless, of okra. The diffusion coefficient of dried okra pieces gave satisfactory results, (16.49-22.72) ×10 -10 m 2 .s -1 for cylindrical samples and (6.24-15.59) ×10 -10 m 2 .s -1 for longitudinal slices. These findings are consistent with the literature. I.

“…Thus, indepth studies have made it possible to correct the weaknesses of this technique as well as those of solar equipment, known as indirect solar dryers, with a plan collector [1][2][3]. These improvements do not always achieve the desired temperature level and drying time [4].…”
